Abstract

The invention produces a smoke screen particularly suited for exercise purposes consisting of a non-toxic aerosol which has no toxic effects on humans and animals and is non-polluting. This is achieved by a so-called pyrotechnical composition with the following constituents: a light metal powder, preferably magnesium powder (Mg) as a metallic reducing agent, potassium nitrate (KNO3?) or a mixture of potassium nitrate (KNO3?) and potassium perchlorate (KClO4?) as the principal oxidizing agent, at least one carbonate, e.g. calcium carbonate (CaCO3?), potassium hydrogen carbonate (KHCO3?), sodium hydrogen carbonate (NaHCO3?), potassium carbonate (K2?CO3?), sodium carbonate (Na2?CO3?) and nitrogen separating substances as combustion moderators as well as at least one sublimate or vaporizable fog-forming non-toxic additive.

Description

Pyrotechnisehe Mischung zur Erzeugung eines Tarnnebels Pyrotechnic mixture to create a camouflage fog

Die Erfindung betrifft eine pyrotechnisehe Mischung zur Erzeugung eines Tarnnebels.The invention relates to a pyrotechnic mixture for producing a camouflage mist.

Derartige Mischungen sind an sich bekannt. Dabei werden hygroskopische Verbindungen, wie Metallchloride (ZnCl2, FeCl3, AlCl3l TiCl4, SiCl4) oder Phosphoroxide (P2O3, P2O5) erzeugt und verdampft, die dann mit der Luft hydrolisieren und zum Tarnen geeignete Nebelwolken bilden. Über den Mechanismus dieser Nebelbildung siehe: H. Ellern, Military and Civilian Pyrotechnics, Chem. Publ. Comp. Inc., N.Y. 1968, S. 147 - 151, John A. Conkling, Chemistry of Pyrotechnics, Marcel Dekker Inc., N.Y. 1985, S. 174, 175.Mixtures of this type are known per se. Hygroscopic compounds such as metal chlorides (ZnCl 2 , FeCl 3 , AlCl 3 l TiCl 4 , SiCl 4 ) or phosphorus oxides (P 2 O 3 , P 2 O 5 ) are generated and evaporated, which then hydrolyze with the air and are suitable for camouflage Form clouds of fog. For the mechanism of this fog formation see: H. Ellern, Military and Civilian Pyrotechnics, Chem. Publ. Comp. Inc., NY 1968, pp. 147-151, John A. Conkling, Chemistry of Pyrotechnics, Marcel Dekker Inc., NY 1985, pp. 174, 175.

Der gebildete Nebel, besonders aus hexachlorethanhaltigen , sogenannten HC-Nebelsätzen, aber auch aus Phospornebelsätzen ist aufgrund der Hydrolyse an feuchter Luft stark sauer, da vor allem Salzsäure (HC-Nebel) und Phosphorsäuren gebildet werden, und deswegen toxisch und pflanzenunverträglich.The mist formed, especially from so-called HC mist packs containing hexachloroethane, but also from phosphorus mist packs, is highly acidic due to hydrolysis in moist air, since hydrochloric acid (HC mist) and phosphoric acids are formed, and is therefore toxic and plant-intolerant.

Darüber hinaus wird bei der am häufigsten verwendeten Nebelmischung auf der Basis von Hexachlorethan (HC) und Zink oder Zinkoxid das Schwermetall Zink in die Umwelt eingetragen. Es hat nicht an Versuchen gefehlt, diese Nachteile zu beseitigen. So sind die pyrotechnischen Nebelsätze der Patentschriften DE-PS 27 43 363 und DE-AS 28 19 850 so aufgebaut, daß die Säurewirkung der erzeugten Nebel durch entsprechende chemische Komplexbildung oder Neutralisierung des gebildeten ZnCl2 oder der Phosphorsäuren teilweise oder ganz aufgehoben wird. Es blieb jedoch weiterhin bei der Erzeugung toxischer, umweltunverträglicher Stoffe.In addition, with the most commonly used fog mixture based on hexachloroethane (HC) and zinc or zinc oxide, the heavy metal zinc is released into the environment. There has been no shortage of attempts to overcome these drawbacks. Thus, the pyrotechnic fog sentences of the patents DE-PS 27 43 363 and DE-AS 28 19 850 are constructed so that the acid effect of the mist generated is partially or completely eliminated by appropriate chemical complex formation or neutralization of the ZnCl 2 or phosphoric acids formed. However, the production of toxic, environmentally incompatible substances continued.

Aufgabe der Erfindung ist es daher, einen besonders für Übungszwecke geeigneten Tarnnebel herzustellen, der aus einem ungiftigen Aerosol besteht, das also weder toxische Wirkung auf Menschen und Tiere ausüben kann, und andererseits umweltverträglich ist. Bei Nichtverwenden des wahlweise genannten NaCl besteht der Nebel hauptsächlich aus für Pflanzen geeigneten Makronährstoffen.The object of the invention is therefore to produce a camouflage mist which is particularly suitable for training purposes and which consists of a non-toxic aerosol, which therefore cannot have a toxic effect on humans and animals, and on the other hand is environmentally compatible. When the optional NaCl is not used, the mist mainly consists of macronutrients suitable for plants.

Die zur Lösung der gestellten Aufgabe notwendigen wesentlichen Merkmale der Er f indung sind im Patentanspruch 1 genannt. Die Unteransprüche nennen Ausführungsarten der Erfindung.The essential features of the invention necessary to achieve the object are stated in claim 1. The subclaims list embodiments of the invention.

Durch die Erfindung wird ein ungiftiger Nebel ausreichender optischer Dichte gebildet.A non-toxic mist of sufficient optical density is formed by the invention.

Die Nebelbildung erfolgt auf folgende Weise: Die Komponenten Magnesiumpulver, Kaliumnitrat und Kaliumperchlorat ergeben bei einer Umsetzung im Bereich von 2500º bereits nebelartige Wolken. Die Nebeldichte wird besonders durch den Anteil von Kaliumchlorid und/oder Natriumchlorid, deren Sublimationspunkt bei 1500 bzw. Kochpunkt bei 1450ºC weit unterhalb der Reaktionstemperatur der Umsetzung von Magnesium und Kaliumnitrat liegen, verbessert. Die Reaktionsprodukte der chemischen Umsetzung aus Magnesium mit Kaliumnitrat, Kaiiumperchlorat, Calciumcarbonat etc. bilden dadurch mit dem sublimierenden Kaliumchlorid oder dem verdampfenden Natriumchlorid einen brauchbaren Übungsnebel ohne toxische oder umweltunverträgliche Inhaltsstoffe.Fog formation occurs in the following way: The components magnesium powder, potassium nitrate and potassium perchlorate result in fog-like clouds when converted in the 2500 ° range. The fog density is particularly characterized by the proportion of potassium chloride and / or sodium chloride, whose sublimation point at 1500 or boiling point at 1450 ° C are far below the reaction temperature of the reaction of magnesium and potassium nitrate. The reaction products of the chemical conversion from magnesium with potassium nitrate, kaiium perchlorate, calcium carbonate etc. form a useful training fog with the sublimating potassium chloride or the evaporating sodium chloride without toxic or environmentally incompatible ingredients.

Die chemischen Reaktionen im Nebelsatz können vereinfacht in nachstehenden drei Gleichungen wiedergegeben werden:The chemical reactions in the Mist Theorem can be simplified in the following three equations:

1. 2 KNO3 + 5 Mg → 5 MgO + K2O + N2 + E1. 2 KNO 3 + 5 Mg → 5 MgO + K 2 O + N 2 + E

2. KClO4 + 4 Mg → 4 MgO + KCl + E2. KClO 4 + 4 Mg → 4 MgO + KCl + E

3. CaCO3 + 2 Mg → CaO + 2 MgO + C + E3. CaCO 3 + 2 Mg → CaO + 2 MgO + C + E

Die bei den drei genannten Grundumsetzungen freiwerdende Energie (E) dient zur Sublimation/Verdampfung von Kaliumchlorid und Natriumchlorid.The energy (E) released in the three basic conversions mentioned serves for sublimation / evaporation of potassium chloride and sodium chloride.

Zur Verbesserung der Abbrandsteuerung werden der Mischung insbesondere Stickstoff abspaltende Substanzen, wie Azodicarbonamid, Oxamid oder Dicyandiamid beigemischt. Dadurch wird ein kontinuierlicher Gasstrom zum besseren Transport der Aerosolpartikel und eine höhere Aerosolausbeute erzielt, da die permanent gebildeten Gase ein Zusammenfließen der Schlacke verhindern und durch Oberflächenvergrößerung die Sublimation und Verdampfung fördern. Beim Abbrand der Mischung entsteht ein rein weißes Aerosol, welches hauptsächlich aus den Komponenten Kaliumchlorid, Magnesiumoxyd, Calciumhydroxyd, Calciumcarbonat, Natriumchlorid und Kaliumcarbonat besteht. Diese Komponenten sind umweltverträglich und ungiftig und bis auf NaCl Makronährstoffe für Pflanzen.To improve the combustion control, in particular nitrogen-releasing substances such as azodicarbonamide, oxamide or dicyandiamide are added to the mixture. This results in a continuous gas flow for better transport of the aerosol particles and a higher aerosol yield, since the permanently formed gases prevent the slag from flowing together and promote sublimation and evaporation by increasing the surface area. When the mixture burns off, a pure white aerosol is formed, which mainly consists of the components potassium chloride, magnesium oxide, calcium hydroxide, calcium carbonate, sodium chloride and potassium carbonate. These components are environmentally friendly and non-toxic and apart from NaCl macronutrients for plants.

Der pH-Wert des erzeugten Nebels ist an der Entstehungsstelle am höchten (9). Durch chemische Umsetzungen der primär erzeugten Oxide K2O und CaO (Gleichungen 1, 3) mit Bestandteilen der Luft, vor allem H2O und CO2 unter Bildung von KHCO3, K2CO3, Ca(OH)2 und CaCO3 und durch Verdünnung, nimmt er schnell ab und erreicht im Abstand von 5 - 10 m von der Nebelquelle den pH-Wert der Umgebungsluft (≈ 6).The pH of the generated fog is highest at the point of origin (9). Through chemical reactions of the primarily generated oxides K 2 O and CaO (equations 1, 3) with constituents of the air, especially H 2 O and CO 2 to form KHCO 3 , K 2 CO 3 , Ca (OH) 2 and CaCO 3 and by dilution, it quickly decreases and reaches the pH value of the ambient air at a distance of 5 - 10 m from the fog source (≈ 6).

Als Anzündmischung kann ein pyrotechnischer Satz mit den gleichen Komponenten wie die Mischung zur Erzeugung des Tarnnebels verwendet werden, bei dem jedoch der Gehalt an Magnesium und an Oxydationsmittel zur Steigerung der Anzündempfindlichkeit und Übertragungssicherheit erhöht ist. Der Anzündsatz kann z. B. aus folgenden Anteilen bestehen: 25 % Mg, 35 % KNO3, 10 % KClO4, 20 % CaCO3, 10 % KCl.A pyrotechnic mixture with the same components as the mixture for producing the camouflage mist can be used as the ignition mixture, but in which the content of magnesium and oxidizing agent is increased to increase the sensitivity to ignition and transmission reliability. The primer can e.g. B. consist of the following proportions: 25% Mg, 35% KNO 3 , 10% KClO 4 , 20% CaCO 3 , 10% KCl.

Nebelsatz und Anzündsatz werden in an sich bekannter Weise in Hülsen gepreßt und mit herkömmlichen Anzündmitteln zur Reaktion gebracht.The mist set and the ignition set are pressed into sleeves in a manner known per se and reacted with conventional ignition means.

Die Zeichnung zeigt eine Ausführungsform eines Nebelkörpers mit der neuen Mischung. In einer Hülse 1 mit Boden 3 befindet sich die verdichtete Mischung 4, welche als Abschluß die mit aufgepreßte Anzündmischung 5 trägt.
